Answer:4x>2+3x+5
Step-by-step explanation:
12x>3+8x>2+9x>2+21x+10
12x>3+8x>2+9x>2+6x+15×10
4x^2(3x+2)+9x^2×6x
4x^2(3x+2)+3x(3x+2)+15x+10
4x^2(3x+2)3x(3x+2)+5(3x+2)
Cancel
3x+2(4×^2+3x+5)
_____________
3x+2
4x^2+3x+5
Answer:
x = 38
∠P = 26º
Step-by-step explanation:
The sum of the angle in a triangle is 180
x + (x + 78) + (x - 12) = 180
Combine like terms
3x + 66 = 180
Subtract 66 from both sides
3x = 114
Divide both sides by 3
x = 38
-----------------------
∠P = x - 12
∠P = 38 - 12
∠P = 26º
Would it be
(2r-7)*(2r+7)
?
A and B are correct because 96/100 is equivalent to 0.96, which is also 96%.
